Title: High energy photon-neutrino interactions

Abstract

A general decomposition of the amplitudes for the 2{r_arrow}2 processes {gamma}{nu}{r_arrow}{gamma}{nu} and {gamma}{gamma}{r_arrow}{nu}{bar {nu}} is obtained using gauge invariance and Bose symmetry. The restrictions implied by this decomposition are investigated for the reaction {gamma}{gamma}{r_arrow}{nu}{bar {nu}} by computing the one-loop helicity amplitudes in the standard model. In the center of mass, where {radical} (s) =2{omega}, the cross section grows roughly as {omega}{sup 6} up to the threshold for W-boson production, {radical} (s) =2m{sub W}. Astrophysical implications of very high energy photon-neutrino interactions are discussed. {copyright} {ital 1998} {ital The American Physical Society}
